You are correct the guns are based on a ratio system, not the actual count.
Vauban did fortfy Toulon. From Wikipedia:
"Beginning in 1678, Vauban constructed an elaborate system of fortifications around Toulon." http://en.wikipedia.org/wiki/Toulon#Vauban.27s_Fortifications
Froim Vauban's Bio on Answers.com:
"In addition, he built fortified naval bases at Dunkirk, Brest, Le Havre, Rochefort, and Toulon to support Colbert's plans for the creation of a powerful navy."
Here is a map from the 1793 Siege that shows some of the gun positions. Very formidable, with inner and outer harbors:
For a detailed description of the port and fortifications, see the whole artcile (Chapter VII)
Here is a good article from Britanica that talks about Colbert's (Naval Minister to Louis XIV) improvements of Toulon: "He refurbished the hospitals in each of the major ports; rebuilt the arsenals at Toulon "
Here is a direct reference to a port fort rebuilt by Vauban: " The Rade of Toulon is one of the best natural anchorages on the Mediterranean, and the largest rade in Europe. A naval arsenal and shipyard was built in 1599, and small sheltered harbor, the Veille Darse, was built in 1604-1610 to protect ships from the wind and sea. The shipyard was greatly enlarged by Cardinal Richelieu, who wished to make France into a Mediterranean naval power. Further additions were made by Jean-Baptiste Colbert and Vauban.
..... Fort Saint Louis, which was reconstructed by Vauban" see http://www.smso.net/Toulon
Ulimately, here is the best reference: Michel Vergé-Franceschi, Toulon - Port Royal (1481-1789. Tallandier: Paris, 2002.) But I don't have it and it is in French...
So Please Matrix, upgrade the guns to what it was in EiA... They should not have dropped.
Most important of all, it makes for a better game.
